How StableUSD (USDS) Works

At its core, StableUSD follows a familiar principle in decentralized finance: over-collateralization.

Stability Mechanism

USDS maintains its peg through:

• Collateral-backed issuance (ETH, BTC, and real-world assets)

• Dynamic risk parameters set by decentralized governance

• Automated liquidations to protect system solvency

Users mint USDS by locking collateral in vaults. If the collateral value drops too much, liquidation mechanisms activate to preserve the system’s balance.
